Live working - Protective clothing against the thermal hazards of an electric arc - Part 1-2: Test methods - Method 2: Determination of arc protection class of material and clothing by using a constrained and directed arc (box test) (IEC 61482-1-2:2014); German version EN 61482-1-2:2014

Title (German)

Arbeiten unter Spannung - Schutzkleidung gegen die thermischen Gefahren eines elektrischen Lichtbogens - Teil 1-2: Prüfverfahren - Verfahren 2: Bestimmung der Lichtbogen-Schutzklasse des Materials und der Kleidung unter Verwendung eines gerichteten Prüflichtbogens (Box-Test) (IEC 61482-1-2:2014); Deutsche Fassung EN 61482-1-2:2014

Overview

This standard describes procedures to test material and garments intended for use in heat and flame-resistant clothing for workers if there is an electric arc hazard. In contrast to the test procedures in IEC 61482-1-1, a directed and constrained electric arc in a test circuit is used to classify material and clothing in two defined arc protection classes. The following modifications have been made with respect to DIN EN 61482-1-2 (VDE 0682-306-1-2):2007-12: a) new mean values of main control parameters arc energy and incident energy based on an extended statistical database; b) reduction of the validity ranges of the main control parameters from double to single standard deviation; c) determination of the incident energy by averaging the two sensor values of a test (instead of considering each single sensor value); d) information on precision (repeatability and reproducibility) of the test method; e) clarification of the scope; f) selection of the arc protection classes (test classes) by the amount of the arc energy and incident energy instead of the short-circuit current; g) permitting electrode design without bores; h) recommendations for the heat-resistant materials to be used for the test box and test plate; i) clarification of the conditions for cleaning and replacing the test box; j) indication of the difference values ΔEi of the transmitted energy values to the Stoll limit value at Tmax and the information if the heat curves of transmitted incident energy exceed the target curve during the evaluation period in the test report; k) preconditioning of the samples according to the manufacturer's instructions. The responsible committee is DKE/UK 214.3 "Ausrüstungen und Geräte zum Arbeiten unter Spannung; Körperschutzmittel und schmiegbare Schutzvorrichtungen" ("Equipment and apparatus for work on electrically energized system; personnel protective equipment and moulded protective devices") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
